fc-loadtool help: improve language regarding 16 MiB flash chips
In FC project history, 16 MiB flash originally meant Pirelli DP-L10.
Then we got FCDEV3B with the same flash (our own design), but now we are
discovering more Calypso devices that used such large flash, both late
Calypso era (Sony Ericsson K2x0) as well as much earlier ones (FIC FLUID
devices.txt file with 2004 dates, Leonardo+ rev 5). Hence we need to
migrate to more generic or neutral language in associated documentation,
without giving elevated status to specific examples that drove our
early project history.

# The most basic ringtone included in TI's TCS211 delivery was apparently # intended to consist of alternating 800 Hz and 900 Hz tones, although # the actual output was a continuous 99 Hz tone as a result of interface # mismatch between the BZ_Tone() driver function and the tone generation # tables. # # In 2016 we made FC Magnetite emit actual 800 Hz and 900 Hz tones, # or rather the closest approximations to these two frequencies that # can be produced in BU mode - see ring.buz example. In 2021 we are # looking into the possibility of switching from BU mode to PWT mode; # the present melody file is a test of how the closest PWT counterpart # to 800/900 Hz would sound. g5 64 12 a5 64 12 g5 64 12 a5 64 12 g5 64 12 a5 64 12 g5 64 12 a5 64 12 g5 64 12 a5 64 12 g5 64 12 a5 64 12 g5 64 12 a5 64 12 g5 64 12 a5 64 12 g5 64 12 a5 64 12 g5 64 12 a5 64 12
